Welcome

Welcome to The Third Manifesto (TTM),
by Hugh Darwen and C.J. Date, our proposed foundation for future
database systems presented in Databases,
Types, and The Relational
Model: The Third Manifesto, 3rd edition,
Addison-Wesley, 2006 (ISBN: 0-321-39942-0). Minor revisions to the
Manifesto
given in Database
Explorations (2010) are reproduced here.

Thanks also to Lyle Hopkins, who redesigned the entire website in
August, 2012.

Our
aim in the third edition has been to provide a text more suited to
university courses, by reducing the polemics, enhancing the tutorial
material, and adding exercises to each chapter. Solutions to the
exercises are available to authorized instructors, in softcopy only, at
the publisher's Instructor Resource Center. At this site we publish
additional material related to TTM
and answer questions that visitors are invited to submit by e-mail.
